World Map of National Residential Radon Levels

The World Map of National Residential Radon Levels provides an overview of residential radon levels by continent and by country, where the data is available. The map compares the radon levels measured by Becquerel per cubic meter (Bq/m3), a measurement of radon in the air, between countries and continents, ranging from low levels of radon at 7 Bq/m3 to high levels at 184 Bq/m3. This map provides an easily accessible and understandable method of demonstrating the most at risk regions of high radon exposure which is known to cause approximately 10% of lung cancers.
